So I'm hardly an authority but from what I've read it seems like sociopaths (psychopaths) are born not made. But most sociopaths are not violent and the inability to feel empathy is not the same as an inability to distinguish right from wrong.

I don't know if your abuser T was a sociopath but I don't think he deserves your empathy. Maybe something bad did happen to him. But something really terrible happened to you and yet somehow you manage to make it through each day without going around raping people. So do I. So do the overwhelming majority of survivors of sexual violence.

There is nothing that could have happened to him that compelled him to do what he did. If he was a T he necessarily had the knowledge that what he was doing was egregiously wrong and had the resources to get help. He didn't just make a small error in judgement or have a bad day.
